netgraph has a full ascii command parser built into it to allow arbitrary
decoding of command messages to as-yet unbuilt modules.
New modules supply a grammar to parser for commands they want to accept.
It's proved invaluable. it's possible to load a new module, and immediatly
control
it from the command line using the ngctl program, even though the
ngctl program knows nothing about the module.
It also knows about several special types including IP addresses
and MAC addresses.
